But there definitely still is a race between modules in there somewhere. The HVR-950Q tuners use several: xc5000, au8522, au0828, .. and unless au0828 is loaded *last*, with a delay before/after, the dongles don't always work. Preloading all of the modules before allowing hardware detection seems to help. Even just changing from a mechanical hard drive to a very fast SSD is enough to change the behaviour from not-working to working (and sometimes the other way around). I tried to track this down a couple of years ago, and found cross-module calls failing because the target functions hadn't been loaded yet. But my lack of notes from 2-3 years ago isn't helpful here. Here's a similar report from 2 years ago, as valid today as it was then: http://www.mythtv.org/pipermail/mythtv-users/2010-January/279912.html Cheers -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
